Survival rate and failure characteristics of the all metal post and core restoration

TLDR

A retrospective cohort of 516 cast post‑and‑core restorations in 283 patients, followed from 1970 to 1990, was assembled from dental records of senior‑student‑treated cases. Ten‑year survival was 82% for anterior teeth, with recementation (46%) and rerestoration (32%) as the most common failures, while posterior teeth exhibited a comparatively higher survival rate.

Abstract

In this retrospective study 516 teeth restored with a cast post and core build‐up were followed from 1970 till 1990. The data was derived from the dental records of 283 dental clinic patients treated by senior students. The survival rate was found to be 82% after 10 years for post and cores in the anterior region. The most frequent failure characteristic was recementation (46%), followed by rerestoration (32%). The solitary provisions in posterior teeth showed a relative high survival rate, compared with other tooth‐types and locations.
